KX 41 Rake Needed (see pic)

Boy one of these would be handy. Can anyone suggest a manufacturer of a rake suitable for my 3500 lb. machine? This one is made in England and they WONT ship one. Yes, I can tooth material out of a pile pretty good with an 18" bucket, but this would be used to scarify hard ground prior to topdressing and or seeding. I would be aiming for approximately 2" of penetration.

Also - what about a small concrete breaker for my 41. Kubota actually makes a small breaker especially matched to the machine. My question is - how productive are these small breakers? Will they break up 6" concrete? Is it extra hard on the machine to use a breaker - seems like it would vibrate a lot.
